ROBZHT KBIlTBR Incorporated, New Jersey. Shuttle stick machine

The present invention relates generally to Embroidery machines and, more particularly, to an improved type of embroidery machine and control system for such a machine.

The known Schiff cben embroidery machine has a common gate frame on which two trays arranged in tandem, one above the other, are attached. Every car has a supply pipe, a <if which a supply of the to be embroidered material is wound up, as well as another tube on which the embroidered material is wound, whereby the material during the embroidery process is stretched between the tubes. The Oatterrahmen can be moved both vertically and horizontally in such a way that the material can be loaded in one by the automatic Control of the machine certain complicated path can be moved. The embroidery devices are in relatively stationary locations with respect to the ones in question ffagen arranged and each has a needle rail with a row of fixed on the needle side of the material Needles which are arranged at juxtaposed locations along the rail and each of which by one Supply of needle thread is supplied. A shuttle box rail is attached to the shuttle string of the material provided that a grater in the longitudinal direction of each other spaced soot box accordingly each of the needles carries, the shuttle boxes containing shuttles which are internally provided with bobbins which

for the torrat on shuttle thread for the concerned Take care of needle threads. At the top of the material is furthermore a tube tip rail is provided that corresponds to the length according to, is provided at spatially separate locations with a number of Bohrepiteen, which in certain Intervals while the machine is in operation to cut holes in the tissue. B's facilities are provided to the needle rail in one To guide the stitch-forming stroke in such a way that the needle threads are brought through the material and loops form, through which the boats in question are passed, so that the shuttle thread through the needle thread is looped. For certain patterns actuates the drill bit rail during the machine cycle to cut the material; in such cases the holes cut in this way are bordered by the interaction of the needles and shuttles.

The needle thread is fed to the corresponding needles via a thread tensioning and control system which, one after the other, starting from the torra roll of the needle thread * Has Kurzhubfadträger and a Langfaubfadträger. The short- and long-stroke thread carriers become effective when the needles move over the goalie or stitch-forming type, in order to initially release the needle threads with practically no tension to then form a loop through which the boats go when the needles move begin to pull back around finally the needle thread tighten backwards so that the stitches are completed will.

From the above it follows that a tax system, that the required coordinated movements of the needles,

Shuttles, drill bits and thread carriers must necessarily be relatively complicated. Except, The fact that the ladles, shuttles, drill bits or thread carriers have to be brought into and out of engagement is furthermore During the machine cycle, change the speed of the machine bu to the depth of the drill bits to control and the gate frame both horizontally ale also move vertically. The control system should be very flexible because the machine is sufficiently versatile A is supposed to be in order to deal with the various types of embroidery designs that are required from day to day. The control problem is further complicated by that practical commercial versions of this machine are relatively large and usually one Have a length sufficient to process approximately 14 m wide fabric. Due to the length of the machines 1st it is often necessary to move the actuators for the stitching tools lengthways at spaced apart locations to be provided twice for the machine. Each such actuator can be controlled and coordinated in the overall machine cycle.

Ss is well known, the different actuations

devices and controls of the shuttle embroidery machine from a common machine of the typical jacquard Coordinate construction from. The machine is generally characterized by having a continuous roll of paper or similar material which known as a hole or control strip that runs along spaced apart locations and a number of adjacent rows corresponding to the different Control functions is punched, which are to be sensed and to be supplied to the actuating devices of the embroidery machine are. The control functions are sensed via pens,

which engage in the holes of the perforation and the control functions in the order in which they are read from the perforation. The perforation is incremented for each stitch, so that a continuous. Reading out the control information for the embroidery machine is obtained.

When using mechanical controls for reading out the information from the machine and carrying it out the necessary associated functions in the embroidery machine and the interlocking of these punctures, in order to ensure a correct working sequence of the numerous devices of the embroidery machine, jedoph Difficulties arise. This can in part be proportionate great sensitivity due to automatic machines on the one hand and the rather large machine that is involved in the mechanical controls for the embroidery machine, can be attributed. In general, it is necessary to have relatively long mechanical links to use with their game, their high inertia and the friction inherent in them. Furthermore, a high degree of precision is required in the mechanical connecting links, with one in order to avoid malfunctions firm guidance is required. As a result, the working speed of the embroidery machine found a limit and it was practically impossible to speed up the work Increase the bias of china in order to obtain increased productivity at lower costs, since mechanical Controls at increased speeds proved to be highly hateful.

With the relatively new emergence of essentially electrical and electronic controls for various types of automatic systems have been used in some

Make Sedanken hired the mechanical ones Replacing controls with electrical counterparts in order to potentially operate at high speed, more economical production and larger To achieve reliability. Electrical control systems, while generally applicable, are not necessarily required practical, including problems of wear, heating and relatively poor flexibility with respect to those used in the embroidery machine Throw facilities on. For example, should magnetic controls be used to puncture the in- and Bringing the stitch tools into engagement, including to effect the needle shuttles and drill bits such magnetic controls in a relatively short time Would experience millions of actuations over time and would be subject to far greater mechanical wear, than they are for commercially available units is pulled. Furthermore, such megnet controls would if they are operated at the frequency required to carry out the automatic functions for an embroidery machine, the noise and turmoil with the generate disadvantages resulting therefrom. Hydraulic systems have also been investigated and can in general ™ do not respond to the speeds required for automation of embroidery machines.

In general, it is an object of the present invention to provide an improved control system for an embroidery machine which avoids the above-mentioned difficulties In particular, the invention takes into account a tax, to create a system that has the characteristics required to perform the coordinated punctures of a To achieve embroidery machine, but together from home with such embroidery machines and their operating environment

The shuttle drive rail 2o is attached to the relatively stationary shuttle box rail 16 via a number of drive rail support shafts 228 which are received in bearings 23o attached to the rail 16. The upper ends of the corresponding support shafts 228 are attached to the shuttle drive rail 2o by means of a Suasatücka 232 which is attached to the rail 2o is firmly attached. The shuttle drive rail 2o is moved by means of a reciprocating drive rod 234 which extends the length of the machine and is driven by the main camshaft 64, as detailed in connection with the Pig. 8-11 is explained. The reciprocating drive train 234 for the shuttle drive shaft 2o is nipple on this by means of a crank lever 236.
